I don't even know why you're considering a galaxy watch, Clearly what you want is a fitness watch and that's not what wear os has ever really focused on. It does a respectable job and is useable but its primarily for the 2 things you don't need. I run all the time and my fossil sport does the job for what I want when it comes to tracking my run and switching songs during a run but I wanted it primarily for previewing calls and responding to texts when at work and not taking out my phone. I daily drove a ticwatch GTH for a couple of weeks and disliked it because its more fitness-focused feel and lack of useful daily features, Thus get the Fitbit since thats what youre looking for.
